It depends on what you mean by “including LGBT+ characters”. Brandon has two gay characters, but I wouldn’t personally say that his books have good representation, as those two characters are very minor in the scheme of things. Lots of books do this, and it’s still rare to find a queer lead or major character, especially in fantasy.
As for the list, I don’t think there would be anything definitive out there, but I think it’s worth noting that for every one book with positive explicit queer representation, there are many more with no rep or negative rep.
